The Sleep Cycle alarm clock is a bio-alarm clock that analyzes your
sleep patterns and wakes you when you are in the lightest sleep
phase. Waking up in the lightest sleep phase feels like waking without
an alarm clock - it is a natural way to wake up where you feel rested
and relaxed. Since you move differently in bed during the different
phases, Sleep Cycle uses the accelerometer in your iPhone to monitor
your movement to determine which sleep phase you are in.

Have you ever woken up feeling completely wrecked when the alarm clock
goes off, despite the fact that you have slept "enough" hours? When this
happens you have probably been awakened during a deep sleep phase, and
your whole day can turn into one long zombie marathon.
Other days you spring out of bed with a smile on your face, feeling
completely rested even though you shouldn't. As the alarm clock goes
off, chance seems to play a big role in how your day will become. But
does it really have to be that way? This is where the Sleep Cycle alarm
clock application comes into play.

During the night you go from light sleep to deep sleep, occasionally
entering into a dream state which is called REM-sleep. These are things
that your normal alarm clock does not care about, and will go off at the
set time regardless of whether you are in a light sleep phase or in the
deepest sleep. However, since you move differently in bed during the
different phases, the Sleep Cycle alarm clock is able to use the
accelerometer in your iPhone to monitor your movement and determine
which sleep phase you are in. Sleep Cycle then uses a 30 minute alarm
window that ends at your set alarm time and wakes you in your lightest
sleep phase.

Using robotics, laser rangefinders, GPS and smart feedback tools, Dennis Hong is building a car for drivers who are blind. It's not a "self-driving" car, he's careful to note, but a car in which a non-sighted driver can determine speed, proximity and route -- and drive independently.

As web companies strive to tailor their services (including news and search results) to our personal tastes, there's a dangerous unintended consequence: We get trapped in a "filter bubble" and don't get exposed to information that could challenge or broaden our worldview. Eli Pariser argues powerfully that this will ultimately prove to be bad for us and bad for democracy.

We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack -- a sonic composition that records some of the most dramatic events in outer space.

Today medical scans produce thousands of images and terabytes of data for a single patient in mere seconds, but how do doctors parse this information and determine what's useful? At TEDxGöteborg, scientific visualization expert Anders Ynnerman shows us sophisticated new tools -- like virtual autopsies -- for analyzing this myriad data, and a glimpse at some sci-fi-sounding medical technologies in development. This talk contains some graphic medical imagery.

Brain-computer interfaces (BCI) based on Steady State Visual Evoked Potential (SSVEP) can provide higher information transfer rate than other BCI modalities. For the sake of safety and comfort, the frequency of the repetitive visual stimulus (RVS) necessary to elicit an SSVEP, should be higher than 30 Hz. However, in the frequency range above 30 Hz, only a limited number of frequencies can elicit sufficiently strong SSVEPs for BCI purposes. Consequently, the conventional approach, consisting in presenting various repetitive visual stimuli having different frequency each, is not practical for SSVEP based BCI functioning. Indeed this would bring low communication bitrates. In order to increase the number of possible repetitive visual stimuli, we consider modulating the phase of the stimulus instead of the frequency. Thus, several stimuli, sharing the same frequency, but with different phase can be presented to the user. The approach presented in this document, to detect the phase of the stimulus is termed phase synchrony. It consists in using as feature, the phase difference between the SSVEP and the stimulus. The phase is extracted through the Hilbert transform applied on an univariate signal resulting from spatially filtering the electroencephalogram. The spatial filter is determined in such a way that the SSVEP energy is enhanced through a linear combination of the signals recorded at different positions on the scalp. Phase detection accuracy for seven subjects ranges from 70 to 94%.

You say tom-ATE-to. I say tom-AHH-to. You say ECG. I say EKG. But which is correct? We asked some people who ought to know.

"They are synonymous. In the U.S. we like to do things differently.
Instead of kilometers we like miles per hour. Instead of kilograms we
use pounds. So we say EKG in the U.S. but in the rest of the world,
it's ECG," said Gordon Huckestein, CEO of Cardiac Direct, Ventura,
Calif. His company is a distributor of the equipment as well as
offering its own brand of you-know-whats.

"When you're talking about a machine, it's six of one and a
half-dozen of the other. It's like the difference between a car and an
automobile. Even if EKG is wrong, people still say it," suggested
Garret Purrington, president of Medical Equipment Dynamics, Inc. (MED).
The New Bedford, Mass. company sells a variety of new and used medical
equipment.

But before we call the whole thing off, consider the nuances. Some
equipment dealers drew important distinctions in how they use the
terms. For instance, some people say EKG when referring to the
free-standing units used in most doctors' offices. However, they may
say ECG when referring to PC-connected heart monitors; or the more
advanced, continuous vital signs monitors used at the bedside in
hospitals. Someone even suggested that new machines be called ECGs and
older ones EKGs.

The trouble may go back to the origins of the technology. The
concept for measuring the electrical impulses of the heart can be
traced back to British research. But the practical use of the EKG dates
to Dutch Nobel Laureate Willem Einthoven, credited with inventing the
electrocardiogram in 1903. The Dutch spelling is elektrocardiogram, hence EKG. This convention continued with German research and development of the technology.

But none of this explains the misguided English usage today.

"In Europe they say ECG; in America EKG. People are confused.
People market it differently. But there is no difference between ECG
and EKG," said John Gladstein, sales manager for Medical Device Depot,
a new equipment distributor in Ellicott City, Maryland.

So why do Americans often say EKG? In English, it would make more sense to say ECG.

"If you spell it in English, it's with a "c." EKG is an
older acronym," said Steve Kenan, senior category manager for
cardiopulmonary devices at Welch Allyn, known for its, ahem, ECG
technology.

"I grew up in India, I never heard EKG before I came here
[to the U.S.]," explained Meera Gopalakrishnan, global product manager
for ambulatory ECG at Philips Healthcare.

"If we have to choose, I would prefer ECG because we don't
see people with Kardiac diseases, we don't record eleKtrocardiograms,
or do eKhocardiograms," offered Bulent Buyukoglu, M.D., a cardiologist
who is manager of USmedevice, LLC, a global ECG distributor based in
Cumberland, RI. "I think ECG is the korrect choice," Dr. Buyukoglu
quipped in an email to DOTmed News.

Professional terminology seems to favor ECG. But for some reason, patients and families in the U.S. nearly always say EKG, perhaps a throw-back usage that has come into layman's acceptance.

"I actually slant my terminology depending on the audience. In
Europe, the German influence is much stronger so they tend to
universally refer to it as an EKG because the German translation is
spelled with a "k" [elektrocardiogramm]. In America,
electrocardiography is spelled with a "c" so ECG is the more formal
approach," explained Meera's colleague Kevin Geary, global product
manager for Philips Pagewriter Cardiographs. (Note their unimpeachable
choice of product category.)

"If you go through the literature, American journals and the American College of Cardiology will be consistent with ECG. Having said that, most hospitals, if they have one, have an EKG Department," he said.

On second thought, let's call the whole thing off.

However, they stay
